Twitter updated its TweetDeck app for Mac today with a few new enhancements. The new version finally adds support for autocompletion of usernames when mentioning other users. Also new in the latest version is an in-line reply composer that allows you to create replies to tweets right in your timeline without having to open a new tweet panel.
Speaking of the tweet composer, it has been overhauled in this version. Instead of a popup window, the new composer has a column of its own with all of the usual options. The panel closes automatically as you send a tweet, but can be optionally set to stay open at all times, making composing a new tweet a much quicker process. In-line replies can also be “popped out” to the composer panel to apply additional options like scheduling. The new tweet panel also allows you to preview your tweet before you send it so that you know how it will look on the web and in Twitter’s official apps.
You can get TweetDeck for Mac for free from the Mac App Store.
